Intel® Gigabit ET and EF Multi-Port Server Adapters

Dual- and quad-port Gigabit Ethernet server adapters designed for multi-core processors and optimized for virtualization

· High-performing, 10/100/1000 Ethernet connection · Reliable and proven Gigabit Ethernet technology from Intel Corporation · Scalable PCI Express* interface provides dedicated I/O bandwidth for I/O-intensive networking applications · Optimized for virtualized environments · Flexibility with iSCSI Boot and choice of dualand quad-port adapters in both fiber and copper

The Intel® Gigabit ET and EF Multi-Port Server Adapters are Intel's third generation of PCIe GbE network adapters. Built with the Intel® 82576 Gigabit Ethernet Controller, these new adapters showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimization for server virtualization. The I/O technologies on a multi-core platform make use of the multiple queues and multiple interrupt vectors available on the network controller. These queues and interrupt vectors help in load balancing the data and interrupts amongst themselves in order to lower the load on the processors and improve overall system performance. For example, depending upon the latency sensitivity of the data, the low level latency interrupts feature can bypass the time interval for specific TCP ports or for flagged packets to give certain types of data streams the least amount of latency to the application.

Designed for Multi-Core Processors

These new dual- and quad-port adapters provide highperforming, multi-port Gigabit connectivity in a multi-core platform as well as in a virtualized environment. In a multi-core platform, the adapters support different technologies such as Intel® QuickData Technology, MSI-X, and Low Latency Interrupts, that help in accelerating the data across the platform, thereby improving application response times.

Optimized for Virtualization

The Intel Gigabit ET and EF Multi-Port Server Adapters showcase the latest virtualization technology called Intel® Virtualization Technology for Connectivity (Intel® VT for Connectivity). Intel VT for Connectivity is a suite of hardware assists that improve overall system performance by lowering the I/O overhead in a virtualized environment. This optimizes CPU usage, reduces system latency, and improves I/O throughput. Intel VT for Connectivity includes: · Virtual Machine Device Queues (VMDq) · Intel® I/O Acceleration Technology1 (Intel® I/OAT) Use of multi-port adapters in a virtualized environment is very important because of the need to provide redundancy and data connectivity for the applications/workloads in the virtual machines. Due to slot limitations and the need for redundancy and data connectivity, it is recommended that a virtualized physical server needs at least six GbE ports to satisfy the I/O requirement demands.

This new generation of PCIe Intel® Gigabit adapters provides improved performance with the next-generation VMDq technology, which includes features such as loop back functionality for inter-VM communication, priority-weighted bandwidth management, and doubling the number of data queues per port from 4 to 8. It now also supports multicast and broadcast data on a virtualized server.

Intel® I/O Acceleration Technology

Intel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration across the platform, from networking devices to the chipset and processors, which help to improve system performance and application response times. The different features include Intel QuickData Technology, Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others. Intel QuickData Technology, a DMA engine, moves data using the chipset instead of the CPU. DCA enables the adapter to pre-fetch data from the memory cache, thereby avoiding cache misses and improving application response times. MSI-X helps in load-balancing I/O interrupts across multiple processor cores, and Low Latency Interrupts can provide certain data streams a non-modulated path directly to the application. RSS directs the interrupts to a specific processor core based on the application's address.

Virtual Machine Device queues (VMDq)

VMDq reduces I/O overhead created by the hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon.2 VMDq technology makes use of multiple queues in the network controller. As data packets enter the network adapter, they are sorted, and packets traveling to the same destination (or virtual machine) get grouped together in a single queue. The packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.

End-to-end Wired Security

The Intel Gigabit ET and EF Multi-Port Server Adapters are Intel's first PCIe adapters to provide authentication and encryption for IPsec and LinkSec. LinkSec is already designed into the network adapter hardware. These adapters are future proof and prepared to provide LinkSec functionality when the ecosystem supports this new technology.

IPsec provides data protection between the end-point devices of a network communication session. The IPsec offload feature is designed to offload authentication and encryption of some types of IPsec traffic and still delivers near line-rate throughput and reduced CPU utilization. LinkSec is a new IEEE industry-standard feature that provides data protection in the network. The IEEE 802.3ae and IEEE 802.3af protocols provide hop-to-hop data protection between two network devices in the transaction line between the host and destination. The two network devices must support the LinkSec technology. The network devices could be servers, switches, and routers.

On-Board Management Features

The Intel Gigabit ET and EF Multi-Port Server Adapters enable network manageability implementations required by IT personnel for remote control and alerting (IPMI, KVM Redirection, Media Redirection) by sharing the LAN port and providing standard interfaces to a Board Management Controller (BMC). The communication to the BMC is available through an on-board System Management Bus (SMBus) port. The adapter provides filtering capabilities to determine which traffic is forwarded to the host.
